Also, another problem is that the pj_thread_desc is currently allocated
on the stack (it's an automatic variable), you should allocate it from
the C runtime heap using malloc, or from a pj memory pool. Here is an
alternative method to use, originally provided by Jim Gomes on pjsip
forum. It leaks some memory every time it registers a thread.
PJ_DEF(pj_status_t) pj_thread_auto_register(void)
{
pj_status_t rc;
if(!pj_thread_is_registered())
{
pj_thread_desc *p_thread_desc;
pj_thread_t* thread_ptr;
p_thread_desc = (pj_thread_desc *) calloc(1,
sizeof(pj_thread_desc));
rc = pj_thread_register("auto_thr%p", *p_thread_desc, &thread_ptr);
}
else
{
rc = PJ_SUCCESS;
}
return rc;
}
